You can apply for the CMP (which is the midwifery program) I think Bunbury is out of their area, but they do take out of area women if it works with travel ect, with them you can homebirth or birth at one of their Hospys (but that will mean travel to Perth) Kaleeya is the hospy in Freo (still 90min away) they have water birth. Peel Health campus is a nearer hospital but lat i heard no waterbirth and huge C-Sec rate. Your other options is to put out feelers for an independent MW in the area.

I'm about an hour out of Perth in a different direction, and in the end i decided homebirth in water was more important to me than hospital with the travelling involved but of course thats a very personal decision. I just can't comprehend going back to birthing dry.
